基于basler巴斯勒工业相机驱动5.2内的C++ MFC的demo，在连续采集图像时，加入了本地存储环节，保存了时间戳

/* Note: Before getting started, Basler recommends reading the "Programmer's Guide" topic in the pylon C++ API documentation delivered with pylon. If you are upgrading to a higher major version of pylon, Basler also strongly recommends reading the "Migrating from Previous Versions" topic in the pylon C++ API documentation. This sample illustrates the use of a MFC GUI together with the pylon C++ API to enumerate the attached cameras, to configure a camera, to start and stop the grab and to display and store grabbed images. It shows how to use GUI controls to display and modify camera parameters. */ #include "stdafx.h" #include "GuiSample.h" #include "GuiSampleDoc.h" #include "AutoPacketSizeConfiguration.h" #ifdef _DEBUG #define new DEBUG_NEW #endif std::string GetTimeStr() { SYSTEMTIME st; GetLocalTime(&st); int ih = st.wHour; int im = st.wMinute; int is = st.wSecond; int id = st.wDay; int imo = st.wMonth; int iy = st.wYear; int iss = st.wMilliseconds; char ctmp[256]; sprintf(ctmp, "%04d%02d%02d_%02d%02d%02d%_04d", iy, imo, id, ih, im, is, iss); return std::string(ctmp); } // CGuiSampleDoc IMPLEMENT_DYNCREATE(CGuiSampleDoc, CDocument) BEGIN_MESSAGE_MAP(CGuiSampleDoc, CDocument) ON_COMMAND(ID_CAMERA_GRABONE, &CGuiSampleDoc::OnGrabOne) ON_UPDATE_COMMAND_UI(ID_CAMERA_GRABONE, &CGuiSampleDoc::OnUpdateGrabOne) ON_COMMAND(ID_CAMERA_STARTGRABBING, &CGuiSampleDoc::OnStartGrabbing) ON_UPDATE_COMMAND_UI(ID_CAMERA_STARTGRABBING, &CGuiSampleDoc::OnUpdateStartGrabbing) ON_COMMAND(ID_CAMERA_STOPGRAB, &CGuiSampleDoc::OnStopGrab) ON_UPDATE_COMMAND_UI(ID_CAMERA_STOPGRAB, &CGuiSampleDoc::OnUpdateStopGrab) ON_COMMAND(ID_NEW_GRABRESULT, &CGuiSampleDoc::OnNewGrabresult) ON_COMMAND(ID_VIEW_REFRESH, &CGuiSampleDoc::OnViewRefresh) ON_COMMAND(ID_FILE_SAVE_AS, &CGuiSampleDoc::OnFileSaveAs) ON_COMMAND(ID_FILE_IMAGE_SAVE_AS, &CGuiSampleDoc::OnFileImageSaveAs) ON_UPDATE_COMMAND_UI(ID_FILE_IMAGE_SAVE_AS, &CGuiSampleDoc::OnUpdateFileImageSaveAs) ON_COMMAND( ID_UPDATE_NODES, &CGuiSampleDoc::OnUpdateNodes ) END_MESSAGE_MAP() // CGuiSampleDoc construction/destruction CGuiSampleDoc::CGuiSampleDoc() : m_cntGrabbedImages(0) , m_cntSkippedImages(0) , m_cntGrabErrors(0) , m_hTestImage(NULL) , m_hGain(NULL) , m_hExposureTime(NULL) { // TODO: add one-time construction code here } CGuiSampleDoc::~CGuiSampleDoc() { } // Initial one-time initialization BOOL CGuiSampleDoc::OnNewDocument() { if (!CDocument::OnNewDocument()) return FALSE; try { // Register this object as an image event handler, so we will be notified of new new images // See Pylon::CImageEventHandler for details m_camera.RegisterImageEventHandler(this, Pylon::RegistrationMode_ReplaceAll, Pylon::Ownership_ExternalOwnership); // Register this object as a configuration event handler, so we will be notified of camera state changes. // See Pylon::CConfigurationEventHandler for details m_camera.RegisterConfiguration(this, Pylon::RegistrationMode_ReplaceAll, Pylon::Ownership_ExternalOwnership); } catch (const Pylon::GenericException& e) { TRACE(CUtf82W(e.what())); return FALSE; UNUSED(e); } return TRUE; } // Some features of USB cameras are of type float (i.e. Gain). // To use the value in Windows controls, we need to convert it to an integer. // This conversion can be done by the GenICam. // All float features have a so-called "alias feature" representing the float value // converted to an integer.
